Shallow-water zoantharians (Cnidaria, Hexacorallia) from the Central Indo-Pacific Reimer, James D. Poliseno, Angelo Hoeksema, Bert W. ZooKeys 2014 444 1 57 7Q3ZW Anthozoa Hydrozoanthidae Terrazoanthus CoL Animalia Terrazoanthus Zoantharia 14 15 Cnidaria genus  Taxon classification Animalia Zoantharia Hydrozoanthidae  Specimens examined (n=1). RMNH Coel 40469, Fauna Malesiana Maluku Expedition station MAL.05, Leitimur, outer Ambon Bay, Tanjung Bentang, Ambon, Moluccas ( 03°35'S, 128°05'E), depth = NA, collected on November 7, 1996 by J.C. den Hartog.  Photographic records (n=1). West Pulau Badi, Spermonde Archipelago, South Sulawesi ( 04°58'06"S, 119°16'57"E), September 29, 1997.  Description. Azooxanthellate. Polyps well free and clear of coenenchyme. Outer surface of polyps covered with dense incrustation of irregularly sized sand particles, reminiscent of Microzoanthussp. Oral disk semi-translucent with dark, almost black coloration, except for oral opening, which is much lighter in color. 40 to 50 tentacles, at least as long as oral disk diameter, with same blackish coloration as oral disk, with terminal 1/4 whitish in coloration. Colonies attached to non-living substrate. Specimen RMNH Coel 40469 is apparently a fragment of a whole colony, while the photographic record shows a colony of approximately 50 polyps arising from a common coenenchyme (Figure 14A). The single specimen had polyps averaging 6.8 mm in length (n=3) and 3.1 mm in width (n=6).  Figure 14. Images of Terrazoanthusspecies from photographic records in this study. A and B Terrazoanthussp. 1 at the west side of Pulau Badi, Spermonde Archipelago, South Sulawesi, September 29, 1997; and C and D Terrazoanthussp. 2 at the west side of Bone Lola shoal, Spermonde Archipelago, South Sulawesi, April 22, 1998.  Distribution. Regions recorded in this study (Figure 15). Spermonde Archipelago (9), Moluccas (14). Previous records. None, although similar undescribed specimens have been photographed in the Philippines (P. Poppe, pers. comm.), and collected from Okinawa, Japan (Reimer, unpubl. data), indicating a potential West Pacific distribution.  Figure 15. Distribution of Terrazoanthusspecies from specimens and photographic records from this study. Terrazoanthussp. 1 specimens in red, and Terrazoanthussp. 2 in green. Region numbers correspond to locations given in species'information. Boxes indicate presence of specimens (with or without photographic records), while circles indicate only photographic records. Overlapping symbols indicate the same region.  Remarks. This species is similar in appearance but different in coloration to Terrazoanthus onoifrom the Galapagos and west coast of Central and South America.
